you're almost there Colludium !!... but (i'm an horrible bugs'hunter):
1/ when the player jump in the pit, the player don't fall... he's stop by an invisible floor (in the pit, it's funny) 3~4sec delay and go to the last checkpoint
2/ you still have a probleme with the fish, i test with the following event:
jump and grab the rope -> release -> falling to the water'edges -> climb the border -> fish visible -> grap the rope and finish in skeleton on the rope.. (flying fishs? lol)
3/when player push the skeleton -> fall down and grab -> the skeleton fall in first and grab continue with skeleton behind the player (funny to push nothing and the skeleton follow the player.
that's all (for the moment)
feel free to say "stop finding my bug" ^^
